How do i enable my DVD-rom's DMA?

[Beautiful Alone]

I heard that if you enable DMA, it will speed up your DVD ripping process.
anyways, how do i enable it?

[Crow]

Go into Device Manager and under either IDE ATA/ATAPI controllers or DVD/CD rom drives cant remember which one but one of those has the setting.

Thats for windows XP not sure with OS your running?

[Beautiful Alone]

yeah, i'm on XP.

Theres a Primary IDE channel and a secondary IDE channel. so ..which one is right for my dvd-rom?

it already saids "DMA if available" soo..does that mean it's already turn on?

does ebable DMA really make a differents?

[Crow]

There's a DMA on both the primary and secondary, check them both.

I've read here that it does i get pretty good ripping speed about 8 or 9x and mine settings appear to be the same as yours check both the primary and secondary to see what they say?

Let me know

[Beautiful Alone]

It saids DMA if available, does that meant it's ebabled?

[Crow]

Right underneath Transfer mode there should be Current transfer mode

What do you have showing in that bar?

[Beautiful Alone]

it saids on the Primary IDE channel ultra DMA mode 4

on secondary IDE channel multi-word DMA mode 2

[Crow]

Then it should be enabled , what kind of ripping sppeds are you getting...not very good if your asking i guess?

[Mirror_Image]

it saids on the Primary IDE channel ultra DMA mode 4

on secondary IDE channel multi-word DMA mode 2

In that case, it would seem that DMA is enabled.

[Beautiful Alone]

In that case, it would seem that DMA is enabled

oh really? could you give me a alittle more info on why it's enable?

well...i'm ripping a DVD movie as we currently speak right now, and it's on 1.6x speed.

[Crow]

Other wise you would not have a DMA under current transfer mode therefor DMA available...hence the enable DMA if available

1.6x OUCH!

[Crow]

Does my last post make any sense???

[theboywonder]

Yes crow, your post did make sense.... its just that Beautiful Alone can't seem to grasp the concept of when it says

"Current transfer mode: ultra DMA mode 4"

...or whatever, that it actually means DMA is being used ... lol

My DVD drive is 10x and rips at a mere 1.2-1.4x with DMA enabled (win 2000). Not sure why. Rips at 4x-5x in Win ME.

I'm sure there is some sort of fix for this. Something about Windows 2000 / XP not actually enabling DMA despite it saying so.... lemme run and check..... brb

[theboywonder]

hmmm.
couldnt find that thing i read before .... only some other info.

from what i could see beautiful alone, make sure you have the correct motherboard drivers installed (esp. if you have an AMD processor - I'm just gonna install mine now cause I can't remember doing it when I reformatted!).

Oh, and DMA enabled in your BIOS settings somewhere.... don't ask lol...

[bigred3]

hi im having same problem as the guy who started topic, under my primary driver it says current trasfer mode pio or whatever, and i can't change it it won't let me, as im only getting about 2ks for dvd speed wich is kind of funny because when i first started ripping dvds i use to get 8 or 9k/s , anybody help me he he

[Boooooommm]

Make sure "DMA if available" is selected on all 4 IDE channels. Then try changing your CD and DVD drives to the Secondary IDE port, and your HardDrives to the Primary. Make sure you set the jumpers on the drives right, or you're gonna have some bad ass problems...

After that start Windows XP/Windows 2000 and the problem should be fixed. XP and 2k don't like Disc drives as slaves on the Primary IDE channel....

That's what I did, and it worked for me Now I'm ripping at 5x average. It all depends on the DVD I'm ripping.

ASPI layer?

[theboywonder]

Well, as for me, I have Compel Aspi installed.

Without it smart ripper wont even open the vob files!

Still, ripping for me sucks in Win2000.
